SAFETY INK-WELL.

Patented Apr. 22, 1913.

Serial No. 713,607.

To all whom it may concern:

Be it known that I, ARTHUR E. VVILDE, a citizen of the United States,residing at New York city, in the county of New York and State of NewYork, have invented new and useful Improvements in Safety Inkells, ofwhich the following is a specification.

The general object of the invention is to prevent the spilling of thecontents of an ink bottle in the event of the upsetting of the saidbottle while in use, and to admit of the insertion for a predetermineddistance of the pen point into the ink when the pen, as a whole, isintroduced into the mouth of the bottle. And to this end the inventionconsists in a valve wholly located within the ink bottle and adapted toautomatically seal the passage through the neck of the bottle and toyield or open for a predetermined distance under ordinary pressure onthe pen when the latter is inserted into the neck of the bottle.

Other objects will appear and be better understood from that embodimentof the invention of which the following is a specification, referencebeing had to the accompanying drawings forming part hereof and in whichFigure 1 is a vertical longitudinal section, showing an inkbottle andthe device assembled therewith. Fig. 2 is a detail perspective of thedevice with the free end portion of the spring broken away.

The bottle a is of ordinary construction and has the usual neck 1) intowhich is inserted the ordinary cork or stoper, (not shown), which formsthe closure when the bottle filled with ink is placed for sale on themarket.

The device forming the subject matter of the present invention consistsof a bushing 5 of cork, rubber or other suitable material and of suchsize as to snugly fit within the neck I) when the original cork orclosure is removed. Assembled with the bushing 5 is a tube 6 preferablyof metal and of such diameter as to admit of its insertion through thehole in the bushing 5 which operates to hold the tube in position afterthe same is adjusted vertically. The tube is of such length as to admitof its lower end extending to a point in juxtaposition to the bottom ofthe bottle a, when its upper end is substantially flush with the upperend of the bushing 5.

A valve 7 formed of any suitable material such as rubber, and bypreference circular in contour and greater in diameter than the diameterof the tube 6, is arranged below and yieldingly held in contact with thelower end of the said tube by a hair pin shaped spring 8, the ends ofwhich are con nected to the valve and to a suitable bracket or lateralextension 9 carried by the tube 6. A stop 10 carried by one of the armsof the spring 8, has an angularly bent free end portion 11 which extendsoverand is normally spaced from the other arm of the said spring 8 so asto contact with the said other arm when the valve is opened for apredetermined distance and thus serves to limit the opening movement ofthe valve.

In use and with the original stopper removed from the neck 5 and withthe bushing 5 removed to the upper end of the tube 6, the device istilted so as to direct the spring 8 into the neck Z) and into the bodyof the bottle a. This done, the device is turned so that the tube 6 willoccupy an upright position and the spring 8 extend horizontally orsubstantially so after which the bushing is forced into the neck 5 andthe tube adjusted so as to have the valve 7 at the upper surface of thebody of fluid. hen it is desired to wet the pen with ink, the pen isdirected downwardly through the tube 6 and until the point contacts withthe valve 7. This done, the pressure is increased until the valve 7moves away from the lower end of the tube, and continued until the bentportion 11 contacts with one arm of the spring. The valve will now beimmersed in the ink and so too, will the lower portion of the pen point.Upon lifting the pen from the tube, the valve will follow under theaction of the spring 8 and thereby seal the tube.

In order to prevent the running out of the tube in the event of thebottle being accidentally upset when not in use, of any ink which may belifted into the tube by the valve during its closing movement, aclownwardly inclined flange 12 is provided and arranged in the upper endportion of the tube. This will form an abutment for ink flowing on theside of the tube when the bottle is upset. A plurality of teeth 13 areassociated with the edge of the flange l2 and are arranged so as tocontact with the pen holder when inserted and taken from the tube 6,whereby to prevent ink from the pen holder from contacting with the wallof the tube.

What I claim as new is A safety device for ink bottles comprising abushing adapted to fit in the neck of the ink bottle, a pen receivingtube adjustably fitted in the bushing, a valve, a hair pin shaped springhaving one arm connected to the tube and its other arm connected to thevalve and arranged for holding the valve normally in contact with thelower end of in presence of two witnesses.
